Indian Standard 
SPECIFICATION FOR CUTBACK BITUMEN 

( Second Revision ) 



0. FOREWORD 



0.1 This Indian Standard ( Second Revision ) 
was adopted by the Bureau of Indian Standards 
on 8 August 1988, after the draft finalized by 
the Bitumen, Tar and Their Products Sectional 
Committee had been approved by the 
Petroleum, Coal and Related Products Division 
Council, 

0.2 This standard was published in 1951, and 
was revised in I96I in view of the publication of 
IS : 1201 to 1220-1958*. 

0.3 The Committee responsible for the prepara- 
tion of this standard decided to revise the 
standard in order to update the same in 
accordance with the revised version of IS : 1201 
to 1220-1978*. In the present version, six grades 
of rapid curing type (RC), medium curing 
type ( MC ) and slow curing type ( SC ) have 
been unified into four grades, five grades and 
four grades respectively, which are currently 



produced and marketed in the country. 

0.4 This standard is one of the series of Indian 
Standards on bitumen. Other specifications so 
far published in the series are:

0.5 For the purpose of deciding whether a 
particular requirement of this standard is com- 
plied with, the final value, observed or calcu- 
lated, expressing the result of a test or analysis, 
shall be rounded off in accordance with 
IS: 2-1960*. The number of significant places 
retained in the rounded off value should be the 
same as that of the specified value in this 
standard.

1. SCOPE 

1.1 This standard covers the physical and 
chemical requirements of cutback bitumefh 
produced by fluxing bitumen with distillates of 
petroleum or coal tar for use in road 
construction. 

2. TERMINOLOGY 

2,1 For the purpose of this standard, the defini- 
tions given in IS : 334-1982* shall apply. 

3. TYPES AND GRADES 

3.1 Cutback bitumen shall be of the following 
three types: 

a) Rapid curing ( RC ), 

b) Medium curing ( MC ), and 

c) Slow curing ( SC ). 

3.2 The three types of cutback bitumen shall be 
classified into grades on the basis of inital 
kinematic viscosity and designated as under. 

•Glossiiiy ofterms relating lo buumtin and tar. 



3.2.1 Rapid Curing (RC)— These shall be 
used with aggregates containing practically no 
fine aggregates passing through 2'36 mm sieve 
and shall be classified into four grades with 
following designations; 

a) RC 70, 

b) RC 250, 

c) RC 800, and 

d) RC 3 000. 

3.2.2 Medium Curing { MC )— These shall be 
used with aggregates containing less than 20 
percent of fine aggregates passing through 
2 '36 mm sieve and shall be classified into five 
grades with designations: 

a) MC 30, 

b) MC 70, 

c) MC 250, 

d) MC 800, and 

e) MC3 000. 

3.2.2.1 MC 30 grade shall be used as primer. 



15:217-1988 

3.2.3 Slow Curing (»S'C) — These shall be used 
with aggregates containing more than 20 per- 
cent of fine aggregates passing throught 2'36 mm 
sieve and shall be classified into four grades 
with designations: 

a) SC70, 

b) SC 250, 

c) SC 800, and 

d) SC 3 000. 

4. MANUFACTURE AND SOURCE 

4.1 The material shall be prepared by fluxing 
bitumen with distillate from petroleum or coal 
tar. 

4.2 The source and type shall be stated by the 
manufacturer. 

5. REQTUIREMENTS 

5.1 Rapid curing cutback bitumen shall comply 
with the requirements specified in Table 1. 

5.2 Medium curing cutback bitumen shall 
comply with the requirements specified in 
Table 2.. 

5.3 Slow curing cutback bitumen shall comply 
with the requirements specified in Table 3. 

6. TESTS 

6.1 Tests shall be carried out as described in the 
appropriate Indian Standards specified in col 7, 
8 and 7 of Tables 1, 2 and 3 for rapid curing, 
medium curing and slow curing cutback 
bitumens, respectively. 



7. PACKING AND MARKING 

7.1 Packing — The material shall be supplied 
in drums of Type A or Type, B according to 
18:3575-1977* or as agreed to between the 
purchaser and the supplier, 

7.2 Marking — Each container of bitumen 
shall be legibly and indeUbly marked with the 
following: 

a) Manufacturer's name or trade-mark, if 
any; 

b) Month and year of manufacture; 

c) Type and grade of material; and 

d) Batch number. 



7.2.1 Each container may 
with the Standard Mark. 



also be marked 



Note — The use of the Standard Mark is governed 
by the provisions of the Bureau of Indian Standards Act, 
1986 and the Rules and Regulations made thereunder. 
The Standard Mark on products covered by an Indian 
Standard conveys the assurance that they have been 
produced to comply with the requirements of that 
standard under a well defined system of inspection, 
testing and quality control which is devised and supervi- 
sed by BIS and operated by the producer. Standard 
marked' products are also continuously checked by BIS 
for conformity to that standard as a further safeguard. 
Details of conditions under which a licence for the use 
of the Standard Mark may be granted to manufacturers 
or processors may . be obtained from the Bureau of Itidia 
Standards. 

8. SAMPLING 

8.1 Representative samples of the material shall 
be drawn and their conformity of the require- 
ments to this standard be judged as prescribed 
in Appendix A.

SAMPLING AND CRITERIA FOR CONFORMITY FOR CUTBACK BITUMEN 



A-1. SCALE OF SAMPLING 

A-1.1 Lot — In any consignment all the con- 
tainers of the same type, same grade and 
belonging to the same batch of manufacture 
shall be grouped together to constitute a lot. 

A-1.2 The number of containers to bfe selected 
from the lot shall depend upon the size of the 
lot and shall be in accordance with Table 4.

randomness of selection, procedures given in 
IS : 4905-1968* may be followed. 

A-2, PREPARATION OF TEST SAMPLES 

A*2.1 From each of the containers selected 
according to A-1,2 and A-1,3, a sample 
representative of the material in the container 
shall be drawn in accordance with the methods 
prescribed in IS : 1201-1978t, taking all the 
precautions mentioned therein. All these samples 
from individual containers shall be stored 
separately. 

A-3. NUMBER OF TESTS 

A-3.1 All the individual samples shall be tested 
for kinematic viscosity, flash point and ductility.
